What are the two main groups of garbage and rubbish?

The two main groups of garbage and rubbish are biodegradable waste and non-biodegradable waste. Biodegradable waste includes organic materials, such as food scraps and yard waste, which can decompose naturally. Non-biodegradable waste consists of materials that do not break down easily, such as plastics, metals, and glass. Proper segregation of these waste types is essential for effective recycling and waste management.
